'3 Claims. (Cl. 280* 42) This invention relates to carts. In a more specific aspect, "this invention relates to aportable and collapsible cart. in a still more specific aspect, this invention relates to a portable and collapsible cart having an easily removable bagfsuch cart being particularly desirably used in home laundry operations and being easy to store between times of use. In yet another specific aspect, this invention relates to new connecting and/ or hinging means for pivotally joined frame members.

I Laundry carts and hampersare known in the art,'a'nd I am the inventor of a very good portable hamper. See my United States Letters Patent No. 2,531,520. This portable hamper, while being very useful,"has a disadvantage "in that'i't is 'not foldable or collapsible and will not store in ass'mall'a space as my new cart or hamper between times of use. My'new collapsiblepo'rtable cart or hamperwhich is the subject hereof is an improvement over my non-folding model which is the subject ofthe patent setforth hereinbefore. The new unique connectin and pinging means'otmy new.'foldable cart, which provides jfor'the very useful ande'asy folding features thereof, is aninv'ention of great 'meritand can be, used to provide folding features for frame members other than thoseus'e'd to support hampers, 'etc., for example, cooking igrills orpans, table tops, serving trays,-and the like.

The new foldable and portable cart of m invention has "an up erffeldabie receptacle support "for supporting a re eeptaeietur ghoutsub's'tanti'ally itsfentire periphery, a pair of base" tubers spaced below this upper support and a pair or frame members extendin between bppesite'margtns "or upport and "said base members.

" are preferably provided by arrarne preferably l 'g'at'e d members, 'a'ri'deach of as annp er portion and alower ortion The upper portions form part, and the lowerpor- 'tweenjtuexsnpport a e. When viewed from the side, one for theeonnectnrg name members is-preferably substantially v'erti'cal between one fof' t'he margins "of the upper suppoft and'the' base, and the other of the connecti'n g frain'e members rerabiy has' asu'bstantially vertically X'te'hdi-ngiipperportioh depending from the other of the 'mar ins, and'allower "portion extending at an angle "to the'v'ertical to'forr'na runner surface. These frame inembe'i 's fandthe foldable "support are pivotallyjoined nothat be disposed in an open-position with the jb'a'se jnetnber's's'paeeu apartjand the support in substantial- 'iy aghdrrzontatpla'ne,and in a :position with the base members relatively close -together and the support member folded to result in a relatively narrow folded ass "bly for" storing in 'a usual narrow "space, for example 'h'etweenarefri'ge'r'ator 'an'dawall. The support carries a rece taclaprrer'ariry a'fre'adil'y removableflbag, in which r is depositedtheitemslheld or' transported by the cart, for

'e'xlamplejlaund'ry. The new fringing means of my invention vfor folding name members which haveportions which aregpivotally connected, such as the upper support frame members and connecting frame members .of my new portable cart, has ahousing having a passageway therethrough. The frame member is mounted in the passageway with the point of pivot within the housing. and with the frame members projecting from the housing. A pin member is mount ed in the housing, and this pin pivotally mounts on of the pivoted frame member portions and connects the frame and housing together. The housing also serves as a stop to position the 'framemembers in desired pivoted, out-of-alignment position. A preferred embodiment of my new means has a housing withspaced passageways so that the folding frame members can be connected'to each other as well as being hinge'dly joined. This is the embodiment desirably employed "'in the. structure .of the .new portable and foldable cart of myinve'ntion.

It is an object of my invention to provide new cart means.

It is another object of my invention to provide new portable and collapsible cart means.

Still another object of my invention is to-provide a new foldable and portable laundry hamper which can be conveniently stored between times of use in a relatively narrow space.

Yet another object of my invention "is to provide new 'hinging means, particularly hinging means for folding frame members having portions which are,piv otally connected.

And, it'is yet another object-of'myiinvention to provide new connecting and hinging means for apair of folding frame members, each having Portions which are pivotally connected.

Other'objects and advantages ofmy invention .of cart means "and connecting and/or hinging means particularly useful therewith will becomeapparentto those skilled in them upon reading this disclosure.

Drawings accompany and are a part-ofthis disclosure. These drawings depict-preferred specific-embodiments of the new means of my invention, and it is'ito be under,- stood thatsuch are not to unduly limit the scope of my invention.

Following is' a discussion and descriptiomof the-new means of my invention made with reference-"to the draw- :ings Whereon the "samereference numerals are used to indicatethe same or 'similarJpartsLoPstructure. The discussion and description is of preferred specific embodiments of my new means, and it :is' to beunderstoodrthat such is not to unduly limit the scope ofamydnvention.

Referring now to Figs. l"through8of thecdrawings which depict preferred specific embodiments .of th'elnew cart and connecting and .hinging .meanstofmy. invention wherein the frame structure of the cart is made from metal rod bent to form the upper frame support members 9 and the lower connecting frame and base members 11. The upper support member rods 9 are preferably bent in arch-like or semi-loop configuration as shown in Fig. 2 so that when they lie in a horizontal plane and end to end, as shown in Fig. 3, they form a receptacle support for snap-on bag 13 and support the bag substantially all around the periphery of the loop support. Bag 13 is preferably made of washable fabric, such as duck or canvas, and readily removable for laundering or replacement. Pockets 15 formed by fabric members sewed to the sides of the bag have been found desirable to hold clothes pins, etc. The bag preferably is held on by snap fasteners 16, the shape of support members 9 determining the top shape of bag 13 when open. The bag 13, of course, folds with the cart.

The lower frame members 11 are made in one piece or in sections, as desired, and they are bent to form front, substantially vertical portions 17 which connect between the upper receptacle support members 9 and base members 19 which are positioned substantially horizontal. The rear portion of members 11 has an upper depending portion 21 which extends substantially vertical, a portion 23 which extends outwardly and downwardly from portion 21, and an angular disposed runner portion 25 which connects with base members 19. These spaced runner members 25 form a runner surface on which the cart rests when being taken up and down stairs. See Fig. 3 of the drawings.

Rear wheels 27 are mounted on axles which are in turn mounted on base members 19 preferably adjacent the runner members 25. Front wheels 29 are mounted on base members 19 adjacent front portions 17 of the frame. These front wheels are preferably caster wheels to make the cart most easy to move and maneuver in any direction, and the cart rides in use on level surfaces on the wheels 27 and 29.

Connecting and hinging means 31, one at the rear and one at the front, connect the four upper and lower frame members together to form the cart frame. On the rear member 31, a bracket 33 is fastened to the housing 35 in a suitable manner such as by riveting the bracket thereto, preferably on the inside thereof. This bracket 33 has spaced holes therein as shown which mount cart handle 37. Handle 37 is adjustably mounted by spring loaded latch 39 which is connected to the upper arm of bracket 33. Latch 39 has a hole therein through which handle 37 will easily pass when the plane of the hole is at right angles to the longitudinal axis of the handle. The spring loading of latch 39 urges it out of this position into a position where the eifective size of the hole is less and the latch contacts the handle to grasp same. Finger pressure exerted on the outer portion of latch 39 works same to release handle 37 for shortening or lengthening, as desired. Handle 37 has a grip of rubber, plastic, or the like, on its outer end to more conveniently handle the cart.

A hanger member 43, on which ironed laundry, etc., can be conveniently hung by the usual clothes hanger, is preferably mounted on the front connecting and hinging means 31, preferably on the outside thereof. A spring loaded removable clamp is mounted on the outside of housing 35, such clamp having spaced holes to receive hanger 43. The clamp end portions snap over the housing, and in at rest position, the top hole grasps the shank of the hanger. Finger pressure downwardly on portion 47 releases the clamp so that hanger 43 can be adjusted as to height or removed. When not in use, hanger 43 can be mounted for storage opposite of Fig. 1 with the outer end projecting inwardly between base members 19.

The new connecting and hinging means of my invention 31 hingedly mounts and connects the pair of upper support members 9 and the pair of lower flame members 11. The ends of members 9 and the corresponding ends of members 11 are flattened and pivotally joined by a teat on one and a recess therefor in the other. See Fig. 7. This ball and socket-type joint has been found particularly satisfactory. The hollow, flat housing 35 has its upper corners open and a pair of spaced holes 36 in the bottom (Fig. 8) and forms spaced passageways in which frame members 9 and 11 are projectedly mounted with their pivoted ends in the housing. Pins 49 are mounted in housing 35 in any suitable manner and pass through holes 51 in the end portions of support members 9 to pivotally attach same and thus members 11 to the connecting means 31.

Housing 35 is made wide enough to accommodate both end portions of the pivotally joined frame members when the cart is in open position, the position of Figs. 1, 3, 4 and 5, and the right hand assembly of pivoted members in Fig. 6. In this position the top of the housing acts as a stop to hold members 9 in substantially horizontal position with base members 19 spaced apart to form a stable base. 1

If desired, the same connecting and hinging means 31 can be used to foldably join frame members for other equipment, for example, a tray or table top which could be hinged to an upper support member similar to member 9, or a cooking grill which could be hinged to a member similar to support member 9, in each case the entire assembly being collapsible to form a relatively fiat package.

As will be evident to those skilled in the art, various modifications of my new cart means, and connecting and hinging means, can be made, or followed, in the light of this disclosure and discussion, without departing from the spirit or scope of the disclosure or from the scope of the claims.
